VALVE.

FL'PECIFICATION forming part of Letters Patent No. 335,221, dated February 2, 1886.

Application filed May 20, 1985. Serial X0. 161L200. (No model.) lnlenled in Germany May 6, 1581, No. 29.373.

To all whom it may concern.-

Be it known that I, ERNs'r Anoos'r CARL GIEBELER, a subject of the Duke of Anhalt, Germany, residing at Berlin, have invented an Improvement in Valves, (for which I have received German Letters Patent No. 29,373, dated November 1, 1884, but taking effect from and after the 6th of May, 1854,) of which the following is a specification.

My invention relates in general to high pressure valves for pipes, tubes, conduits, or fittings thereof for water, gas, and other liquids and fluids, and it is of especial applicability to high-pressure mains for water, steam, and the like.

The object of my invention is the constrnction of a simple and effectual high-pressure valve adapted to be employed as a substitute for the costly and cumbrous arrangements known as "side or by pass valves, and which are generally employed in highpressure mains and other conduits in which it is necessary at times to cut off or isolate branches.

Apparatus embodying a good form of my improvement is represented in the accompanying drawings, and described in this specification, the particular subjectmatter claimed as novel being hereinafter definitely specified.

In the drawings, Figure 1. is a central vertical sectional side elevation of a device embodying my improvement. Fig. 2 is an end view of the same, the valve-body being in sec tion, but the valve disk and stem and a portion of the cap being in end elevation. Fig. 3 is a sectional top plan view taken in a central horizontal plane through the valve-body A. Fig. 4 is afragmentary sectional side elevational detail through a portion ofthe valvedisk, the flanged nut, and its depending sleeve, showing also one of the overhanging jaws and a portion of the valve-stem. In all of the above views the register or relief-port contrivance is represented as closed. Fig. 5

part of the carrying-main.

is erected a cap, 13, at the upper extremity of which is a journal or stiiffingbox, I), of any preferred construction. \Vithin the valvebody is formed a tapering cylindriform valveseat, (1., within which is adapted to be seated a valve disk, 0, which is circular when viewed from either face and tapering when viewed from the side, and which is of a taper corre spondent to that of the valve-seat, so that when introduced therein it is adapted to fitit closely.

The valve-body is provided with vertical ways a, which engage with slidebearings 0", formed on the sides of the valve-disk, so that said valve-disk is guided in its vertical movement by said ways.

The side faces of the valveseat are conveniently provided with circular bearing-plates a", and the side faces of the valve-disk are likewise conveniently provided with circular bearing-plates 0*, the said bearingplates, respectively. registering when the valve-disk is in place and within its seat.

The valve-disk is provided with a series of slots or opening, 0, conveniently formed in a central vertical tubular enlargen'ient, c", which projects upon both side faces of the disk, and which, as to its projecting or bulging portions, is provided with said slots or openings. The valve-disk is also provided with two upwardly-extending overhanging and facing jaws, 0 containing between them a seat, 0, or housing for a nut.

D is a vertical valve-stem extending from the valve-disk through the upper portion of the valve body, through the cap, and through the journal-box I) in the cap, above which it is provided with a squared extremity, d, adapted to receive a key, E, or other contrivance for rotating the stem. The stem is also equipped with a fixed liat collar, (1*, which bears in a boxing, b and serves to swivel the valve-stem and prevent any longitudinal movement thereof when it is rotated. The lower portion of the stem is provided with a screw-thread, and passes through a threaded nut, F, conveniently provided with a squared flanged base, j", which in the set of the parts is entered below the jaws of the valve-disk and within the seat 0, so formed in the supports on said jaws to receive it and to prevent IOO the nut from rotating, although permitting it to move a certain distance up and down.

The nut F is provided with a depending slotted slide, conveniently made in the form of. a tubular sleeve, G, which is fitted within the hollow interior of the tubular enlargement c of the valve-disk. This depending sleeve is provided with a series of transverse slots or openings, upon its sides, which are adapted to register with the slots or openings 0 in the respectivesides of the tubular enlargement 0 The sleeve itself is capable of movement up and down within the tubular enlargement upon the movement imparted to the nut which carries it by the rotation of the threaded valvestem.

Such being a description of the construction of my device, its operation is as follows: 'When the valve is closed, the valve-disk is in its seat, as shown in Figs. 1, 2, and 3 of the drawings, and the nut and its sleeve are down in such manner that the flanged base of the nut is away from the overhanging jaws of the disk, and the slots in the sleeve beyond the slots in the tubular enlargement of the valvedisk, or in such position that the unslotted portions of the sleeve close the slotted openings in the enlargement. When, new, it is desired to operate the valve, the stem is rotated with the result that, as the stem can have no longitudinal movement, the nut is drawn up upon it until its flanged base encounters the jaws and its further movement is stopped,

and the sleeve is thereby raised until its openings register with the openings in the tubular enlargement, and in such manner openings are afforded for the liquid or fluid in the main to flow through the valve-disk. A further rotation of the stem thereafter occasions the gradual lifting of the valve-disk through the contactof the flanged nut with the jaws, and when the valve-disk has been raised to the full extent of its movement the main is open. When it is desired to close the main, the stem is reversely rotated with the result that the valve-disk is gradually moved down until it is deposited in its seat, after which the further continued rotation of the stem causes the gradual creeping down of the nut and its depending sleeve until the nut seats itself in thebottom of its housing and untilthe slots in the sleeve have moved beyond the slots in the tubular enlargement and the valveopenings havebeen entirely closed.

It is obvious that the gradual opening of the slots through the valve-disk by the gradual upward movement of the slotted sleeve affords a gradual relief of the pressure upon the valve, and consequently permits of the ready movement of the sleeve-disk proper, while the fact that the slots remain closed until after the valve-disk has seateditself in the closing of the valve tends to relieve the resistance usually found in the closing of a vertically-moving gate-valve.

I am aware that I am not the first to provide an opening or relief-port through the face of a disk-valve and a device for closing the said opening, and to such an invention, broadly, I lay no claim, as the gist of my improvement resides in the provision, in connection witha series of slots or slotted openings formed directly through the valve-disk, of a correspondingly slotted or opening-provided register-slide, which operates by means of the devices hereinbefore specified, in connection with the said slotted openings. It is of course possible to fashion both the slotted tubular extension and the slotted tubular slide herein set forth to another form than the tubular or cylindric, and possible likewise to form the nut which works upon the threaded stem and the jaws and seat which house and limit the movement of said nut to other shapes than those represented. These changes would, however, be merely formal,and not materially modify the construction of the series of slotted register-openings and the slotted registerslide, broadly, as such.

Having thus described my invention, I claim- 1. The combination of a valve-body, a valveseat in said body, a valve-disk adapted to said seat and provided with slots or openingsthrough it, a valve-stem, a slotted slide or register contrivance for closing the slots in the valve-disk, a nut threaded upon the valve stem and connected with the register contrivance for closing the slots in the disk, and a housing connected with a valve-disk for containing and permitting a limited movement to said nut upon the rotation of said stem, substantially as shown and described.

2. The combination of the valve-body pro vided with the valve-seat, the valve-disk provided with a slotted enlargement and with the nut housing, a threaded valve stem, a nut threaded upon the valve-stem, a slotted sleeve connected from said nut and having a movement within the slotted enlargement of the valve-disk, and a suitable cap or kindred fitting for containing a boxing for the stem.

In testimony whereof I have hereunto signed my name this 7th day of April, A. D. 1885. 1
